Battery reverse polarity - no lights and no dash

[Johnarmentrout]

2007 RS Venture

I had dim lighting and connected battery in reverse for a split second by mistake. Blew the 30 A fuse. But no others that I can see. It will crank. But no dash and no headlight. I’ve not tried to start it.

Do I need a new voltage regulator? Or ecu or ....?????

replaced the fuse?

after that i would start with the ground blocks to fix your lighting issue.

I replaced the 30A fuse as I mentioned. I’ll check the others with a meter tomorrow.
I can’t be the only one that has done this.
Perhaps it’s an easy fix. I hope so.

It hasn’t run since 2013. And I guess I’d forgotten that the lights and dash don’t turn on until it’s started and running.

Primed carbs and it started right up and runs smoothly.
Now for a little clutch maintenance and clean up…

So… when the next guy sees this thread, the only thing that happened was the 30A fuse blew, the one right next to the battery.

I always like when people report back and tell everyone what the problem was, thanks. Glad it was nothing major.
